Title (EN) INGOT MOLD AND METHOD FOR FORMING THE SAME
(FR) MOULE DE COULEE DE LINGOTS ET PROCEDE DE FABRICATION
Abstract: front page image
(EN)An ingot mold (10) provided with means (34) affording stress relief thereto for the ingot pouring operation, while maintaining the mold (10) in condition to aid in preventing metal leakage therefrom during the ingot pouring operation and subsequent cooling of the ingot, and providing mold wall support for the ingot until its skin has sufficient structural integrity to support the molten interior of the ingot, and a mold (10) which can be recycled for use in a faster manner as compared to heretofore utilized solid or one-piece type ingot molds. In certain embodiments, the mold is formed of a plurality of completely separate and individual side wall sections (12, 14, 16, 18) defining at least the side periphery of a mold cavity (28), together with coupling means (34) connecting the wall sections together. The coupling means (34) provide for expansion and contraction of the mold sections (12, 14, 16, 18) relative to one another during the pouring of molten metal into the mold (10), and the resultant heating and subsequent cooling thereof. At least certain of such coupling means (34) comprises adjustable spring means (56a, 56b) able to be preloaded a predetermined extend prior to the pouring operation, and thus providing for predetermined preloading of the openable and closeable junctures between the mold sections (12, 14, 16, 18).
(FR)Moule de coulee de lingots (10) pourvu de moyens (34) permettant le relachement des contraintes pour l'operation de coulee tout en maintenant le moule (10) dans des conditions permettant d'eviter les fuites de metal depuis le moule pendant la coulee du lingot et son refroidissement ulterieur, et offrant au lingot un support suffisant jusqu'a ce que sa peau presente une integrite structurelle suffisante pour supporter l'interieur en fusion du lingot, et moule de coulee (10) qui peut etre recycle pour etre utilise plus vite que les moules massifs ou en une seule piece qui etaient utilises jusqu'a present. Selon certains modes d'execution, le moule est forme d'une pluralite de sections de parois laterales, individuelles et completement separees (12, 14, 16, 18), definissant au moins la peripherie laterale d'une cavite formant moule (28), avec des moyens d'assemblage (34) assujettissant les differentes sections les unes aux autres. Les moyens d assemblage (34) permettent la dilatation et la contraction relatives des sections de moule (12, 14, 16, 18) pendant la coulee du metal en fusion dans le moule (10), et pendant le chauffage qui en resulte et le refroidissement ulterieur. Au moins certains des moyens d'assemblage (34) comprennent des moyens de ressort reglables (56a, 56b) qui peuvent etre precontraints sous une charge determinee avant la coulee, et permettent donc de precharger de facon determinee les jonctions entre les section de moule (12, 14, 16, 18).
